c To all whom it may concern:

Be it known that I, EDWARD O. KnAToa, a citizen of theUnited States of America, and resident of Cincinnati, in the county of Hamilton and State of vOhio, have invented.

a new and useful Improvement in Combined Wire Stretching and Splicing and Drilling Maclnnes, of which the following 18 @SPQCP fication. p l 7 An object of. my nvent on is to produce aportable wirestretching and splicing and drilling machine.

A further object is to produce a wire stretching and splicing and drilling ma chine for use by. concrete contractors inthe erecting of forms, by farmers in the build ing of wire fences, the. baling of hay and other purposes, by box makers in the manufacture of wire bound boxes, by line menin; the'construction of telephone anditelegraphwires, and by others who 'haveoccasmn :to J

l 1 handle wire.

These and other objects are attained in the wire stretching and splicingmachinc described 1n the following specification and illustrated in the accompanying drawings,

in which:

Figure 1 is aside elevation of my im-.

proved machine with wires which have been stretched and spliced, in position therein;

Fig. 2 is a side elevation of the machine disclosed in Fig. 1 and looking in the direction indicated by the arrow A disclosed in Fig. 3 chine, taken from the opposite side disclosed in Fig.2, the machine being shown in use as a power feed drilling machine.

Fig. 4 is a transverse sectional perspective view taken on the line 4t 1 of Fig 1.

Fig. 5 is a perspective view of a winding crank adapted to operate my improved machine. v

Figs. 6 to 9 inclusive, are views of various wire splices accomplished by the use of my improved machine. v

. My improved machine consists of a frame 5 having bearings, 6, 7 8 and 9 adapted to journal the hollow longitudinally extending shaft 10 of a bevel gear 11 whichis coaxial with the axis of frame Extending at right angles to the axis of frame- 5' are bearings 12- and 13 adapted to journal the trans versely extending shaft 1 1 of abevel gear 15 is anelevation of my improved Inawhich meshes with bevel gear Shaft of'bevel gear 15 is provided with a keyway 16, adapted to receive a key 17 of a winding crank 18, see Fig. 5,which isprovided for operating the gears. Adjacent to bearings 12 and 13, additional bearings 19 and 20 are formed in the frame 5,;these bearingsbei-ng adapted to 1ournal transversely extending shaft 21. Shaft 21 is provided with. a keyway 22 for receiving the key 17 of winding crank 18. The inner endof shaft 21 'isprovidedwith an enlargement 23 having a dia metrically extending slot 24: adapted to re-- ceive the wireto be tightened or stretched. Shaft 10 is provided with a longitudinally extending slot 25 which communicates with the hollow interior of the shaft. Located in alinement with the axis of shaft 10 and adapted to register with its hollow interior,

is a lug-26 having a groove 27 adapted to re ceive the wire extending through shaft 10.

In the end of this lug two rollers'28 and 29 are mounted, the end ofthe lug being provided with a'V-shapednotch 3O fora purpose hereinafter to be described. On one 7 side of the lug a set screw 31 is provided; the :set screw being. adapted to be broughtto close the slot 27 to prevent the wires which I have been brought into engagement therewith, from being displaced therefrom. Ad-

jacent toi. this set'screw 31 and located toward gear 11, but entering lug 26 from the opposite side, is another. set screw 32. This set screw 'is so positioned'as to intercept the axis of the frame and consequently to engage the wire or wires occupying the slot 27. In that end of shaft 10 adjacent to lug 26, a set screw 33 is provided. Thisset screw is adapted to move transversely of the slot 25 and to be brought into engagement with.

the wire or wires occupying the slot. Adjacent to the opposite end of shaft 10, and in bearing 'lug 9, a slot 3 lvis' provided a set screw 35 being located adjacent'to bearing 9' for the purpose of intercepting the slot to engage a wire located therein. Extending from bearing h1g9 is the rib 36 onwhich bearing 19 of shaft 21 is formed. This rib. I I

carries a pivotallymounted pawl 37 which is adapted to engage a ratchet 38 secured toi shaft .21. Adjacent to pawl 37 and formed as an integral part of rib 36 is a lug 39' carrying a set screw 40 which is adapted to clasp a wire passing through the machine.

' an integral part of the rib 41 on which bear ings l3 and 20 are provided, is a handle 42 by means of which the machine is held in position. Pivotally mounted on gear 11 and adapt thereof, is a finger 43, see Fig. 4, having its end leladapted to pass-through the slot and to engage an opening $5 on the opposite side of the shaft. The formation and position of this finger is more clearly disclosedin Fig.- 4, Formed on the frame5 and extending from opposite sides thereof, are brackets 4521116. 47 adapted to journal the respective rollers 48 and d9. In shaft 21 be- 7 tween ribs 36 and ll, are formed a series of transversely extendlng apertures 50 adapted to receive'a small hand pin for a purpose hereinafter to be more fully set. forth.

In operation; V It will be assumed that it is desired to stretch and to splice two pieces of wire 51 and 52, such'as disclosed in Figs. 1, 2 and i. To perform this operation, the end of wire 51 is passed through the machine by passing itithrough lug 39, to one side of en larg'ement 23 of shaft 21, through slot 34.

of bearing 9, through slot 25 of shaft 10, and through slot 27 of'lug 26. The opposite wire 52 is passed from the opposite direction through lug 26, through shaft 10., through bearing 9, and its end is brought.

into engagement with'slot24: of enlargement 23 of shaft 21. Set screw 10 then tightened up on wire 51. The winding crank 18 is then placed upon. shaft 21 and the shaft is rotated in such a direction as to wind wire 52 upon its enlargement 23 as disclosed in Fig. 1, pawl 37 in coeperation with ratchet 33, of the wire. shaft 21 the two wires are stretched or tightened to the required amount. Set screw 32jis brought into engagement with the Wires in'slot 27 Finger 43 is then brought so that its end 44: passes between the wires and into engagement with aperture 45 of shaft 10, as disclosed in Fig. 4. The winding crank is then removed from the shaft 21 and placed upon shaft 14. Shaft 1 1 is then rOtated to cause shaft- 10, through the gears 11 and 15, to rotate. This results in the wires being twisted in the manner illustrated in Fig. 6. The machine is now 131beincr removed from between the wires and twisted portion 53 of wire 52, being The maslipped from enlargement 23. chine now being free it may be lifted from the wlres and the wires trimmed by cutting ofi' twistedend 53, straight'end 54.- of wire 51,- and if desired, one side of the loop formed b'y key- ,43, may be cut to prevent "disclosed in Fig. 7.

preventing unwinding movement By the winding-operatlon of the wires untwisting. ,This leaves the stretched and spliced wires in the condition disclosed in Fig. 6.

Should it be desired merely to splice the wires without stretching them, either a short or long splice may be made. To make the ed to engage slot 25 formed in shaft 10' tion.- Winding crank 18 is placed on shaft 14 and shaft 10. is rotated, thus causing the two wires to be twisted together between produce the result set screws 32 and 33 to Should it be desired" to produce a long splice the same operation is performed, except that set screw 35 is utilized as the stationary set screw in place'of set screw 32, set screw 33 again being employed as the rotat ing set screw. The distance between set screws 33 and being greater than between set screws 32 and 33 the splice produced is like that disclosed in Fig; 7

In using my improved machine for the purpose of wiring boxes, the notch 30 is brought into engagement with the corner of the box and the two ends of the wire rollers 28 and 29. This produces the result disclosed in Fig. 9. After the ends have been'trimmed, the. twisted wires are bent down into engagement with the sides of the box. For the purpose of rendering my improved machine easier to operate, espe cially when particularly stiff wire of large diameter is to be handled, I have devised the extension crank, disclosed in Fig. 5. which is composed of two sections 55 and Section 55 carries the handle 57 and section 56 carries the boss 58 adapted to receive the shafts 14 and 21. Any suitable means such as screws 59 and 60 may be provided for securing the sections 55 and 56 in their ad- 3L1St6d positions to render the crank longer or shorter, as desired. i 3

Should a loose and sagging wire be required to be tightened, as is frequentlv found in fences and the like,'the machine is placedupon the wire by bringing its slots 27, 25-and 34; into engagement with the wire and by placing the wire within slot 2410f the wire tightening device. The winding crank is then placed upon shaft '21 and the shaft is rotated so that the wire is wound upon enlargement 23 of the wire tightening passing around the box, are passed through with shaft 1 1 through gears 11 and 15. This 7 clamped by set screwformed therein.

stretched, set screws 40 and 32 are tightened. The wound up wire is then removed from} mechanism. This operation brings that por-' tion ofthe wire which passes lug 39, into such a position thatitwill enter the slot The Wire having been enlargement 23and is straightened out, it being severed at the point where it extends beyond slot 34 of bearing -lug 9. ;The straightened .out'end of the wire is then laid within the slots 34:, 25, 27 and set screws 35.

and 33 are brought into clamping engagement with the parallel ends of the wire.

-Winding crank 18 is then removed from shaft'21 andplaced upon shaft 14, shaft 10 then being rotated because of its connection results in the wires between setscrews 33 and 35- being twisted to produce along The machine may then be'removed set screws 10, 35, 33 and 32, the extending untwisted ends of the wire splice. by releasing fulcrum about Which the machine may be rocked to bring tension to bear upon the wire clamped by set screw 32 and passing through the mold members. After the wire has been stretched, the usual clamp may be placed thereon to hold the mold members in position.

I An 'additonal feature of my improved machine is that I have provided a hook 426 upon handle42 of my machine, so that the machine 'may be conveniently hung-upon Wires or other obj ects' when it would be in-' convenient to find a place to-lay it.

I have so constructed my improved wire stretching and splicing machine, that it may readily be used as a power feed hand drill, the same instrumentalities as are employed for handling wire, being employed when the machine is in use asa drill. This particular use of my improved machine is fully disclosed in Fig. 3. A drill bit of the size of the bore to be made, is placed inv position within slot 27 'of thelmachine'and' passed" into the hollow of sha-ft' l0r Set screw 33 is; f then brought into engagement withthe drill v V shaft 1 1 the shaft may be rotatedv and thus to hold it tightly.y By applying thecrank to caused tooperate the vdrill. However, when it is desired .tous'e the machine "asadrill embodying power p feeding mechanism, I place a wire 62 around the object 63 t0 be '65 drilled, passing. the ends of the wire over 7 the pulleys 48 and '49 and bringing the ends I into engagementwith slot 2 1 of enlargement; 23 of shaft 21'. Crank 18 is then placed'on shaft 21to rotate it and to tighten the wire. Ratchet 38 and pawl 37. coact to retain the wire in its tightened condition and thus place a certain amount iof pressure upon the drill '61.- I By placing crank 18 upon shaft 145, the drill is then rotated until it has entered piece 63 to the point where the tension on wire 62 no longer eXertsany force upon it. The crank is then removed.

and placed upon shaft 21. again to tighten the wire. In this manner the drill may be caused to bear tightly againstthe work to be i .drilled-and thus to workitskway under power through the-piece. Ifdesired, the crank may be left on shaft 14s and a short rod maybe passed through any one of the apertures 50 inlposition to be grasped by the hand of the operator as he takes hold of i the handle 42, thus enabling him to main tain a substantially uniform tension on the wire during operation of rotating the drill.

Whatfl claim is:

' A wire splicing machine comprising a framefa longitudinal"shaftvjournaled in the frame and having a longitudinal wire receiving groove, a transverse shaftmounted 1n the frame at one e1 [d ofthe longitudinal shaft and having a wire receiving groove in it', a stationary lug atthe'oppositeend of the. 1 longitudinalshaft, and having a longitudi- 'nal groove in alinement withthe groove in the longitudinal shaft, a second lug upon its the opposite side of theframe from the first lug, a clamp forsecuring a wire upon each lug, and means for rotating the shafts.

In testimony whereof, I' have vhereunto subscribedmy name this 26th day of March, 1917. i
